And as a prerequisite, it would be great to have a description for most of our characters at all.
But please, restrain yourself ... don't describe much more than what someone passing by would see in a brief glance. When I look at a character in-game and see pages of different detailed outfits to scroll down, and a headline of choice, then I can't help but conclude with the summary: tl;dr
If you are proud of your elaborate dresses, please make reading their description optional for those who want to take time to do so; but in a character description, "wearing an elaborate outfit" should only be one less important attribute of the person inside the clothes. Subtle hints about the general mood, habits, behaviour or even handicaps are much more important.
Details about reasons for some peculiarities (like being imprisoned for years) or even the pedigree belong to the OOC part only. I doubt that you can count the siblings of people by just looking at them. But a haggard face, if at all visible (cloaking is a bad excuse, IMHO), is obvious enough to be described in the C.D. immediately.
